I have tested this version several times to get the balance just right. Too much liquid and it turns soupy, too little cheese and it feels dry. This version bakes up creamy, cheesy, and perfectly sliceable.
Ingredients
For the Beef Layer
- 1 ½ pounds thinly sliced beef steak or shaved beef
- 1 tablespoon olive oil
- 1 medium yellow onion, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 red bell pepper, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
For the Creamy Base
- 4 ounces cream cheese, softened
- ¼ cup beef broth
- 1 teaspoon Worcestershire sauce
For the Topping
- 6 to 8 slices provolone cheese
- 1 cup shredded mozzarella cheese
Ingredient Notes & Substitutions
Shaved ribeye gives the most authentic flavor, but sirloin works beautifully too. Just slice it very thin against the grain so it stays tender.
If you prefer a sharper flavor, swap provolone for white American cheese or even a mild cheddar.
For a dairy-free version, you can try dairy-free cream cheese and cheese alternatives, though the texture will be slightly different.
If you are curious about the history behind this classic sandwich, you can read more about it on the official Visit Philadelphia website. It is such a fun food story.
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
- Heat olive oil in a large skillet over medium-high heat. Add the sliced beef in batches so it browns instead of steams.
- Stir in the onion and bell peppers. Cook until they soften and start to caramelize, about 5 to 7 minutes.
- Add minced garlic, salt, and pepper. Cook for 30 seconds, just until fragrant.
- In a small bowl, whisk together softened cream cheese, beef broth, and Worcestershire sauce until smooth.
- Reduce the heat to low and stir the cream cheese mixture into the beef and vegetables. It should melt into a creamy, savory sauce that coats everything.
- Transfer the mixture to the prepared baking dish and spread it evenly.
- Layer provolone slices over the top, then sprinkle with shredded mozzarella.
- Bake for 15 to 20 minutes, until the cheese is fully melted and bubbly around the edges.
- Let the casserole rest for 5 minutes before serving. This helps it set and makes it easier to scoop.
Pro Tips for Success
- Slice beef as thin as possible for tender bites.
- Cook in batches to get better browning.
- Drain excess liquid before adding cheese if needed.
- Let it rest briefly after baking for cleaner slices.
If your cheese starts to brown lightly on top, that is perfect. Those golden spots add so much flavor.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, warm gently in the oven at 325°F or microwave individual portions until heated through.
Make Ahead & Freezing
You can prepare the beef and vegetable mixture a day in advance and store it in the fridge. Assemble and bake when ready.
This casserole also freezes well. Wrap tightly and freeze up to 2 months. Thaw overnight before reheating.
Tips and Variations
- Add sliced mushrooms for extra depth and texture.
- Stir in a pinch of red pepper flakes for gentle heat.
- Top with chopped fresh parsley before serving for brightness.
- Serve over cauliflower rice for a complete low carb meal.
- Spoon leftovers into lettuce wraps for a fun twist.
